Microsoft gave details on the processors that will run its upcoming Xbox One at last week's Hot Chips conference, but I'm still left with more questions, specifically about how the processor will stack up to the one in Sony's upcoming PlayStation 4 and to existing PC processors. Read More »

While server chips get most of the attention at the annual Hot Chips conference, AMD and Intel used the occasion to talk about the chips they released earlier in the year while giving little more than teasers about the processors yet to come. Read More »

At this week's Hot Chips conference, the most interesting announcements were about high-end processors. These are designed for big Unix-based systems, but they show just how much power today's high-end chips can deliver. They aren't the kinds of systems that most of us run in our corporate server racks or that you see in big scale-out data centers, but rather are the ones that run mission-critical applications in large enterprises, or perhaps in high-performance computing situations.

While Intel and AMD account for most of the volume, a fair number of servers (which make up a substantial part of revenue) run other chip architectures. At the annual Hot Chips conference yesterday, representatives from IBM, Oracle, and Fujitsu discussed the architectures their organizations will use in creating high-end microprocessors, typically used in applications ranging from mainframes to high-performance computing. All of these are large processors and tend to use the most advanced techniques. In addition, Applied Micro showed off what is likely to be the first 64-bit ARM server chip to ship, while Intel detailed its existing Xeon E5 processor. (I wrote about other AMD and Intel's offerings yesterday. Read More »

This week is the annual Hot Chips symposium on high performance microprocessors and, as usual, it is dominated by news from AMD and Intel on both their existing chips and on future processors. AMD probably had the most to discuss, talking about its upcoming Jaguar and Steamroller core designs. Intel disclosed a bit more about its current Ivy Bridge chips and upcoming Xeon Phi (Knights Corner) many-integrated-core design. Read More »
